My invention relates to an ilnprovementin that class of flashlights orbattery handlamps which are constructed so as to preventshOrt-circuiting and the vconsequent wearing out of the batteries incase the lamp is placed in a wire mail-basket or brought into contactwith metal in such a way as to cause shortcircuiting, the object beingVto produce a convenient and reliable lamp of the character described,with particular reference to reduction in the number of parts employed,and to cheapness of construction.

With these ends in view, my invention consists incertain details ofconstruction as e will be hereinafter described and :pointed out in theclaim.

In carrylng out my'lnvention as herein from the contact-rivet -3 to thebatteryspring 4 and hence to the lowerI pole of the battery 5 within thetubularl fiber .case 6, :is insulated by a co-extensive insulatingstrlp7 from the lower housing-rivet 8 of the hous- Specication of LettersPatent.

shown, the lower terminal-strip 2 leading,

ing 9 of the contact-button fixture which is arranged in line kwith thesaid ca-se and secured to the exterior surface thereof by the rivet 8aforesaid, and by rivets 11, 11, which pass through laterally offsettingears 12"of the housing with which theydo not aline as does the rivet 8aforesaidf The batterycase 6 in which the said rivets are mounted, 1s ofinsulating material, but

it stillY becomes necessary to kinsulate the lower terminal-strip 2 fromthe lower housing-rivet 8 under which the strip 2 passes'on its way, soto speak, to the lower endnof-the battery-case.

To eliminate the threaded metal collars ordinarily mounted at therespective ends of the case 6, I form external rolled in or cut screwthreads 13 at theupper' end thereof, -and correspondingly rolled in'orcut external threads 14 at the lower end thereof, the

upper threads 13 providing for the direct,I

application to the case of the lens-ring 15 which holds the lens 16 i'nplace, while the threads 14 provide for *the direct application to thelower end of the case.'

of the bottom-cap 17, which receives a disk A18 of insulating material'for' the insulation from it of the batteryspring 4 whichjs hinged tothe lower end of the terminal-strip 2, formed with a knuckle 19 for suchpivotal attachment. When the battery and cap are in 'place the saidspring is inter'` posed between them as shown in Fig. 2 and connects thebattery with the contact-rivet 3 through the insulated terminal-strip2..

The lower ends of the strips 2 and 7 are fastened to the lower end ofthe case 6 by a.

any approved standard construction'. As

shown it has a lamp 22 inclosedby, and in circuit with a reflector 23 towhich the uppery terminal-strip 24 leads from one of the two offsettingrivets 11 ofthe housing 9. The contact-button fixture ma also be 'ofvany standard construction. I s herein shown, llQ

it is vpiwidea with 'a Sliding button 25, a.

V.push button 26, and a contact-spring 27 which latter 'coacts with thecontact-rivet 3.

The upper pole, of they battery is held circuiting of the battery 5through its lower pense and lighten the device.

terminal strip 2. O n the other'hand, by producing the screw threads 13vand 14 directly in the ends ofthe battery-case 6 for the application ofthe lens-ring 15 and the bottom- .cap 17 I simplify the question ofinsula- 15` tion and 4also dispense with the use of the threaded metalfurrules or rings heretofore employed at these points, and thus save ex-I claim A ashlightorbattery hand-lamp having a'tubular case providedwith external screw threads -formed directly in it at its lower end, acontact-button housing arranged in tact-rivet mounted in the case at apoint within the upper end of the said housing, a Y

terminal-strip arranged in line with ,the housing and extendingtact-rivet' to the lower end of the case, a bottom-cap for the caseapplied directly to the exterior threads formed in the lower endthereof, and a rivet for fastening the lowerend of the terminal strip tothe lower end of the case, the outer end of the said rivet being locatedin a recess formed in the threaded portion of the case, whereby therivet is insulated from the flange of the said cap.
